PROJECT BACKGROUND

PROBLEM STATEMENT

Non– renewable energy is energy which is taken from the sources that are available on the earth in limited quantity and eventually come to extinction. From the movement of the door (open/close), this potential energy can be utilized and transform into other form of energy.

OBJECTIVES

To design a low cost working prototype that can harvest the energy from the movement of the door that act as “independent electricity supplier” to produce clean and safe energy.

METHODOLOGY

DESIGN

• GEAR AND RACK POSITION• MAGNET POSITION• CIRCUIT• CASING

PLAN• OBTAIN MATERIALS AND IDENTIFY REQUIRED TOOLS

• ASSEMBLE THE CIRCUIT, CASING, MOVER AND ELECTRIC GENERATOR

BUILD

TEST

• TEST THE PROTOTYPE USNG MULTIMETER, BATTERY AND LED

EVALUATE

• EVALUATE THE VOLTAGE DUE TO THE MOVEMENT OF THE DOOR

• EVALUATE THE POTENTIAL TO LIGHTEN THE LIGHT EMITTING DIODE

• EVALUATE THE VOLTAGE OF THE BATTERY UPON TESTING THE PROTOTYPE

MECHANISM OF PROTOTYPE No.

Name Description

1 Magnet and coil To convert the electrical energy from kinetic energy produce due to the movement of the door.

2Rechargeable batteries

To store the converted energy inside it. Can be used for other purposes such as light up a bulb, charging mp3 and etc.

3 Rectifier To convert AC current to DC current. The DC current then will be stored inside the rechargeable batteries.

5 Drive Shaft To transmitting the torque and rotation from the movement of the door to the needle within the magnet and coil.

6 Connection wires To connect the electronic parts within the breadboard.

7 Breadboard To be the main board in constructing the test circuit.

8 Switch To connect or break the electrical circuit.

9 Digital multimeter To measure the voltage level, current flow and resistance in the circuit.

10 Plywood To make a mini door as a prototype and as the container of the breadboard.

RECOMMENDATION

CONCLUSION

The basic prototype of Energy Harvesting Door has successfully build and functioning well. Based on the results, Energy Harvesting Door is able to generate electrical energy due to the movement of the door. In terms of achievement, this inventory will possibly lead to an ideal alternative to the electrical energy when there is no power source. In addition, the total cost to the build-up of this project is also reasonable and affordable. Based on the cost provided, a least amount of money that has been spends on this prototype due to the simple materials that has been used. The objective is achieved.
